Answer 1

Liferay allows assigning permissions to roles only, you just cannot do it for single users. You have either define a new role or implement this functionality on your own (not using Liferay's permission system).

Just in case if you would come up with this idea, avoid using creating roles for every user - it is a performance killer. People sometimes try do do this in order to get around the limitations of Liferay's permission system - it is a very bad idea!

Answer 2

This tutorial can help you:

1. You need to create a resource-action-mapping XML file, and add a new action-key (plain string)
2. Put it into /src/main/resources/resource-action (name it as default.xml)
3. Create a portlet.properties file under /src/main/resources
4. Add the following line: resource.actions.configs=resource-actions/default.xml

Deploy your portlet, and check your new permission under Roles -> Select role -> Define permissions tab

You can check the user permissions with the permissionChecker on your JSP

1. You need this import: <%@ taglib prefix="theme" uri="http://liferay.com/tld/theme" %>
2. Define objects: <theme:defineObjects />

3. Now you can use the permissionchecker object:

   permissionChecker.hasPermission(scopeGroupId, portletName, scopeGroupId,    permissionName)
